This Operator used when a NULL value has to retrieve from table or Database.

I Made a table Named 'mgr' Into a database named 'dbase' within the reference of mySql(php myAdmin). Then i import all the mandatory java packages from the java library. Then i made a class named 'MySqlNullCondition', which extends the 'HttpServlet'. I use serviceMethod() which is responsible for getting request from the doGet() method for Output on a web browser. After, then i loaded all required drivers that necessary for database accessing. The next move i declare variable those objects will create a criteria to use database i use 'connection' variable (which will be use to create a connection between database and the java code (actual code). The next variable will be the 'resulSet' (this will be responsible for getting value from the desired column and rows as required). And the next one will be the 'preparedStatement' that will use to executing the query like executeQuery() as (SELECT name,salary,manager_id FROM mgr WHERE manager_id is NULL). At the last instance i use doGet()Method which will use to get output on a web Browser.

We use a tabular form concept. For this kind of requirement, we use ‘HTML’ coding and some of tags to use Output in Designer look to show on a web browser.
